Nickel-plated brass tuning shank for B-flat

In 1884 Edmond Daniel in Marseille developed a three-valve compensating system in collaboration with his former apprentice François Sudre; the system was named "Arban Compensateur" after the famous cornetist.

As specified on this cornet, the purpose of this compensating system was to improve intonation of c-sharp, d, e-flat, a-flat. The main windway enters the third valve and, if no valve is actuated, transits through the second and first valves into the bell. Using the first and second valves on their own or together engages the normal valve loops. Actuating the third valve (master through which the windway passes twice) adds extra tubing. Using the third valve alone or together with the second valve engages the shorter of two extra loops on the first valve (for e-flat1 and a-flat1); using first and third valves or all three valves engages the longer of the two extra loops (for d1 and c-sharp1). The extra loops are reached via either a shorter compensating tube on the bell side or a longer one on the leadpipe side, both bypassing the second valve.
